Over the weekend I read a profile of Christine Lagarde and how she rescued a EU crisis meeting once by passing around a bag of M&Ms (sugar kick) and suggesting to move all documents aside and start writing points of agreement on a blank sheet of paper.
It is incredibly hard to get a large group of people to agree on a complex document (or presentation) on the spot. Sometimes, the list of bullet points is the best solution:
Short informal language
Everyone has full visibility fo what is written
Any distracting side comments can easily be parked
